Chevrolet EXPRESS - 2011 Manual page 334

A Tire and Loading Information
label, attached to the vehicle, shows
the size of the vehicle's original
equipment tires and the correct
inflation pressure for the vehicle's
tires when they are cold. See
for an example of the Tire and
Loading Information label and its
location on the vehicle. Also see
The vehicle's TPMS can warn you
about a low tire pressure condition
but it does not replace normal tire
maintenance. See
,
, and
.
,
The TPMS will not function properly
if one or more of the TPMS sensors
are missing or inoperable. When the
.
system detects a malfunction, the
low tire pressure warning light
flashes for about one minute and
then stays on for the remainder of
the ignition cycle. A DIC warning
message is also displayed. The low
tire pressure warning light and DIC
warning message come on at each
ignition cycle until the problem is
corrected. Some of the conditions
that can cause the malfunction light
and DIC message to come on are:
One of the road tires has been
replaced with the spare tire.
The spare tire does not have a
TPMS sensor. The TPMS
malfunction light and DIC
message should go off once you
re install the road tire containing
the TPMS sensor.
The TPMS sensor matching
process was started but not
completed or not completed
successfully after rotating the
vehicle's tires. The DIC message
and TPMS malfunction light
should go off once the TPMS
sensor matching process is
performed successfully.
See TPMS Sensor Matching
Process later in this section.
One or more TPMS sensors are
missing or damaged. The DIC
message and the TPMS
malfunction light should go off
when the TPMS sensors are
installed and the sensor
matching process is performed
successfully. See your dealer
for service.
